Gradient 0–1 scores based on relationship graphs, activity rhythm, and behavioral fingerprints.
Attestation Chains
Verifiable provenance through linked cryptographic attestations with temporal decay.
Takeover Detection
Behavioral anomaly scoring detects compromised or impersonated agents.
API & SDK
REST endpoints, Python SDK, and CLI for every trust verification workflow.

Why Trust Matters
AI agents are entering the economy at scale — negotiating contracts, managing funds, executing tasks on behalf of humans and other agents. Yet there is no standard way to verify whether an agent is who it claims to be, whether it has a track record of delivering on promises, or whether it has been compromised.
Without verifiable trust, every agent interaction is a leap of faith. Platforms can't distinguish reliable agents from malicious ones. Developers can't build secure multi-agent workflows. Users can't delegate with confidence. The agent economy stalls before it starts.
isnad solves this with cryptographic identity, attestation chains, and behavioral scoring — giving every agent a verifiable reputation that travels across platforms. No central authority. No blind trust. Just math.
